DISK HARROW AND CULTIVATOR.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed August 31', 1918. Serial No. 252,176.

To all whom it may concern:

Be it known that I, ARTHUR BRIGDEN, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented a new and useful Disk Harrow and Cultivator, of which the following is a specification.

This invention has reference to disk harrows and cultivators, and its object is to provide a disk carrier whereby the angle of the plane of the disk to the line of travel may be changed and the tip of the disk to the vera carrier also capable of adjustment about a vertical axis so that the disk may be adjusted about either or both of two axes arranged at right angles one to the other, one being substantially vertical and the other substantially horizontal.

The invention will be best understood from a consideration of the followin detailed description taken in connection w1th the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing Figure 1 is a plan view of a cultivator or harrow embodying the invention.

Fig. 2 is a perspective view of the disk carrier.

5, 6, respectively, for adjusting the bars 3 Y and 4t, and links 7 connecting the levers to the bars. Guide segments 8 serve to support the bars 3 and 4 from the beam 2. No attempt is made to particularly illustrate the body of the cultivator or the operating parts, the invention being directed to the means for mounting the cultivator disks, which latter are indicated at 9 and may be of the usual dished disk type. v

Each disk 9 is carried by a hub 10 having at one end a flange 11 against which the disk may seat and to which it is secured by'rivets Each disk is furthermore mounted on an axle 13 which may turn with the disk, the hub 10 being held to the axle 13 by a countersunk set screw 14 located',in the particular showing of the drawing, on the concave side oft-he disln The axle 13 extends beyond the flange 11 for a suitable distance and terminates in a head 15.

There is also provided a block 16 which may be in the form of a casting bored to be travepsed by the corresponding portion of the axle 13 and countersunk, as shown at 17, to receive the head 15. The opposite end of the bore through the block 16 is countersunk, as shown at 18, to receive a washer 19 surrounding the axle adjacent to the flange 11. By this arrangement the axle or shaft 13 may turn in the block 16 but dust and dirt are excluded from the bearings of the shaft by the head 15 at one end and the washer 19 at the other end. An oil hole 20, indicated in Fig. 3, provides for lubricating the axle where it turns within the block 16.

There is also provided a hanger 21 which may be in the form of a strap with legs 22 converging from a yoke or base portion 23 and terminating at the free ends, which are the lower ends, in substantially parallel extensions 24. embracing the block 16. The extensions 24 are traversed by bolts 25 and 26 respectively holding these extensions close to the block 16 and preventing the spread of the legs of the hanger. The bolt 25 traverses the block 16 at a high point thereof above the axle 13 so that the block is pendently supported. At the lower end the block is provided with an arcuate recess 27 curved about the axis of the bolt 25 as a center and this recess has end walls in the forni of flanges 28 in the path of which is locatedthe bolt 26, the arrangement being such that the block may be swung about the bolt 25 to an extent determined hy the length of the recess 27 between the flanges 28, the axis ofswinging being about the holt,,25.

opposite sides of the upright central axis of the hanger. The slots 29 are traversed by bolts 30 in-the'b-a'rs and 4.

The slots 29 permit individual adjustment 10 of the hangers 21 with relation to the bars 3.; and ee'wh-ileithe levers 5 and 6 permit, mass adjustments of: the, disks; this last feature not. entering into theipresent invention and ww henithewbloclz 16 is tilted as desired, it.
